Percentage of lollipops after Japheth received from Howard
= 100% + 40%
= 140%
Percentage of Japheth's lollipops that Winnie had after receiving from Japheth
= 50% x 140%
=
50100 x 140%
= 70%
Percentage of lollipops that Japheth had left after giving to Winnie
= 140% - 70%
= 70%
100% = 40
Number of lollipops that Japheth had left
= 70% x 40
=
70100 x 40
= 28
